Problems solved by technology

[0003] First, the structure of the transverse bulkhead of an ultra-large container ship is relatively weak. The total section of the transverse bulkhead is only divided in the direction of the ship’s width, and the guide rail frame is installed in the state of turning over, which will result in the guide rail on the transverse bulkhead section The frame often suffers from poor accuracy
[0004] Second, the sections with double-sided guide rail frames are assembled. Due to the long-term shelving, sand washing, and transportation of the sections, the cumulative deformation of the sections is relatively large. During the assembly process, large-scale deformation often occurs. The trimming adjustment phenomenon of the guide rail frame

Abstract

The invention discloses an installation method of a double-faced guide rail used for an ultra-large type container ship transverse bulkhead block. The block comprises a first section, a second section, a third section and a fourth section. The installation method comprises the following steps that the transverse bulkhead block central line and the hatch coaming top plate line are surveyed and marked on an overall assembly platform; a set of docking block positioning central lines and a set of guide rail rack positioning central lines are surveyed and marked in the ship width direction; a set of first waterlines and a block lower edge line are marked in the ship height direction; a plurality of cement docking blocks are arranged according to the hatch coaming top plate line, the first waterlines and the docking block positioning central lines, and a guide rail rack embedded jig frame is installed in a forklift groove between every two adjacent cement docking blocks; a guide rail rack is hoisted into the guide rail rack embedded jig frames; the first section, the second section, the third section and the fourth section are hoisted onto the multiple cement docking blocks and welded; and the guide rail rack is positioned and installed. By the adoption of the installation method, deformation caused by turning-over of the block can be reduced, and the installation accuracy is high.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for installing a double-sided guide rail frame under the condition that the total section of the transverse compartment of an ultra-large container ship does not turn over during the assembly process. Background technique [0002] At present, the container ship is developing in the direction of very large container ship (VLCS), and the size of the transverse bulkhead structure shows a trend of increasing, which leads to the weakening of the rigidity of the total section of the transverse bulkhead. At present, the installation of the guide rail frame of the transverse compartment of the ultra-large container ship is mainly carried out by the following method: the transverse bulkhead is divided into several sections in the direction of the ship's width, and the double-sided guide rail frame in the state of turning over the several sections is respectively carried out. Install, and finally c...
